Keymark Corporation

Keymark Corporation is a privately held aluminum extrusion manufacturer headquartered at 1188 Cayadutta Street in Fonda, with a second plant in Lakeland, Florida. Founded in 1964, the company designs and cuts its own extrusion dies in-house, extrudes custom and stock profiles, and applies finishes including powder paint, wet paint and anodizing.

Building and construction is Keymark’s largest market: its extrusions go into curtain wall, commercial windows and storefront systems for projects such as the Comcast headquarters tower. The company also supplies automotive, consumer durables, electrical, machinery and transportation customers.
